Poly[(dimethyl-formamide)(µ(4)-2,2'-sulfanediyldibenzoato)nickel(II)].

The title centrosymmetric dinuclear Ni(II) complex, [Ni(C(14)H(8)O(4)S)(C(3)H(7)NO)](n), was prepared via reaction of Ni(NO(3))(2)·6H(2)O and thio-salicylic acid, with H(2)O and dimethyl-formamide (DMF) as the mixed solvent. The central Ni(II) ion is five-coordinated by five O atoms from DMF and from the carboxyl-ate groups of the organic ligand. The symmetry-related coordination polyhedra inter-link into centrosymmetric dimeric units and these, in turn, are linked into infinite chains propagating parallel to [100].
